CCBJ Vol I No 11: Energy Storage

CCBJ estimates that storage devices generated $2 billion in revenues in the United States in 2008 through the arbitrage of on-peak/off-peak rates and sales of ancillary services such as frequency regulation. Most revenues were generated by pumped storage hydropower systems, a small amount from the one existing compressed air energy storage plant in the United States, and even smaller amounts from flywheel and battery systems. The market may be small today, but it has enormous potential. In this edition, CCBJ profiles leading energy storage technology developers and interviews storage experts at independent system operators and utilities who view energy storage as a critical enabling technology to integrate large volumes of intermittent renewable power.
